Gallium is produced by the electrolysis of a solution obtained by dissolving gallium oxide in concentrated naoh(aq). calculate the amount of ga(s) that can be deposited from a ga(iii) solution by a current of 0.490 a that flows for 50.0 min.

The mass of gallium produced by the electrolysis is 0.0354 grams.

Explanation:

The equation for the deposition of Ga(s) from Ga(III) solution follows:

where,

C = charge

I = current = 0.490 A

t = time required (in seconds) =    (Conversion factor: 1 min = 60 s)

Putting values in above equation, we get:

where,

C = charge = 147 C

F = Faradays constant = 96500

where,

n = number of electrons transferred = 3

Putting values in above equation, we get:

Moles of Gallium =

Molar mass of Gallium = 69.72 g/mol

Putting values in above equation, we get:

Hence, the mass of gallium produced by the electrolysis is 0.0354 grams.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
